SPECIFICATION forming part of Letters Patent No. 510,435, dated December12, 1893. 1'

Application filed February 25, 1893. Serial No. 463,730- (No model.)

To all whom it may concern:

Be it known that I, JOHN H. MILLER, a citizen of the United States,residing at Batavia, in the county of Kane and State of Illinois, haveinvented a certain new and useful Improvement in Windmill-Vanes, whichis fully set forth in the following specification, reference being badto the accompanying drawings, in which- Figure 1 represents a sideelevation of my vane, showing its attachment to the main casting of thewind mill. Fig. 2 shows a plan of the reverse side of that shown in Fig.1, of a portion of the vane. Fig. 3 shows a top view of the vane, cut insection, at line 33, Fig. 1. Fig. 4. shows a portion of the sheet metalwhen itis out ready to be attached to the frame or bone of the windmill. Fig. 5 shows another portion of the same sheet metal out ready tobe attached to the frame of the vane. Fig. 6 shows a perspective view ofone end of the angle-iron cross-brace of the frame of the vane, thedotted lines showing the end turned down, ready to be bolted to the mainframe or bone of the wind mill.

The object of my invention is to make a strong and inexpensive vane fora wind mill composed of metal.

My invention consists of the devices and combinations of deviceshereinafter fully described and made the subject matter of the claimshereto.

In the accompanying drawings, A represents a portion of the main castingor turntable of a wind mill.

BB are two arms rigidly attached to or forming a part of the casting Ato which the vane is pivoted at 0-0.

D is a vane-iron composed of a vertical piece, E, with two projectingarms or pieces, F-F, which are pivoted tothe arms BB, at C. There arealso arms, GG, one above the other when the vane is in position on themill, and to which the main frame or bone of the vane is bolted, and twoarms or projections, HH, one under the other, to which one end of thebraces for bracing the vane, is bolted. The main frame or bone, I, ofthe vane I make of angle-iron, extending around the vane of the mill,the ends being bolted to the projections or arms GGr of the vane iron D.

I have also an angle-iron cross-brace J. One side of this angle-iron ismade longer than the other, as clearly shown at K in Fig. 6, and bentdown as shown by dotted lines, and then bolted to the main frame or boneI, as clearly shown in Figs. 1, 2, and 3.

L is a sheet-metal piece cut in form to be bent over one of the sides ofthe angle-iron frame or bone I of the vane and of the crossbrace, J,clearly shown in Figs. 1, 2 and 3. This sheet metal piece is cut at thecorners, as shown in Figs. 4 and 5, for the purpose of fitting to themain frame or bone and crossbrace of the vane, and enabling the edge tobe turned over one side of the angle-iron constituting the main frameand cross-brace of the vane. This sheet metal piece is secured to theframe of the vane by turning its edge over one of the sides of theangle-iron which constitute the frame--no riveting being required tohold it in place.

M-M are two braces, one end of each of which is bolted to one of thearms H of the vane-iron D, and the other end of each is bolted to one ofthe sides of the angle-iron frame or bone I of the vane.

The construction of the vane-iron D is such that the main frame or boneI is bolted to it at one side of a center line drawn through the centerof the main casting of the mill and through the point where the vane ispivoted to the main casting, and the braces M brace the vane near itslongitudinal center so as to give it great strength.

My vane is made very quickly by using angle-iron for the main frame orbone of the vane, as well as the cross-brace, and braces MM, and thesheet metal constituting the wind surface of the vane is secured to'thevane frame by turning its edges over and swaging them down, thusobviating the necessity of bolting.

I have alight, very strong and durable vane, susceptible of sustaininggreat wind without injury to the mill.

Having thus described the construction and operation of my invention,what I claim, and desire to secure by Letters Patent, is-

1. In a wind mill vane, the angle-iron main frame or bone 1; theangle-iron cross-brace J, and the sheet metal piece L secured thereto byturning its edges over one side of the angle-iron frame, substantiallyas specified.

2. In a wind mill vane, the vane-iron or casting D having arms orprojections F adapted to bepivoted t0 the main casting or turntable, thearms G--G to which the main frame of the vane is bolted, and the armsI-I-l-I to which the braces of the vane are bolted; the angle-iron mainframe of the vane adapted to be bolted to the arms GG of the vane ironD; and the braces M-M bolted to the arms H-I-I of the vane-iron D and tothe main frame or bone I of the vane, as specified.

3. In a wind mill vane, the angle-iron main frame or bone I; theangle-iron cross-brace J, with one side longer than the other, and bentat right angles and bolted to the main frame or bone I of the vane; thesheet metal piece L with corners cut and adapted to bend over the mainframe and cross-brace, as specified 20 and shown.

JOHN H. MILLER.
